Objective To investigate the modified herniorrhaphy method for adult oblique inguinal hernia. Methods From June 2001 to June 2005,the clinical data of 56 paitients with oblique inguinal her-nias were analyzed retrospectively. Results Rapid recovery,with few complication as well as low cost were achieved.Follow-up time was in 6 months to 5 years.Postoperative recurrence was not found. Conclusion With modified herniorrhaphy,the normal anatomical structure of internal ring were restored and the trans-verse fascia defect are strengthened at the same time. Normal anatomical structure of inguinal canal are main-tained. This procedure possesses a higher cure rate and postoperative recurrent rate may be reduced obviously.

Objective　The aim of this paper was to investigate endothelial dysfunction，platelet activation, and inflammation in elderly hypertensive patients and those complicated with cerebral infarction. Methods　Twenty-eight elderly hypertensive patients complicated with cerebral infarction(within 72 hours after onset of neurological symptoms),thirty-one Stage Ⅰ～Ⅱelderly hypertensive patients and twenty-eight elderly healthy individuals were selected as subjects.Their plasma concentrations of von Willebrand factor(vWF), alpha granule membrane protein-140(GMP-140), and serum concentrations of C-reaction protein(CRP) were examined. Results　Elderly hypertensive patients complicated with cerebral infarction had significantly higher plasma vWF, GMP-140, and serum CRP than elderly hypertensive patients and elderly healthy individuals. Plasma vWF and GMP-140 were higher in elderly hypertensive patients than elderly healthy individuals, whereas serum CRP was increased slightly and there was no significant difference between elderly hypertensive patients and elderly healthy individuals. Conclusion　This study suggests that elderly hypertensive patients complicated with cerebral infarction have obvious endothelial dysfunction, platelet activation, and inflammatory change. Stage Ⅰ～Ⅱ elderly hypertensive patients have obvious endothelial dysfunction and platelet activation as well.

The precocious puberty in female rats were induced by subcutaneous injection of N-methyl-DL-aspartate (NMA). The female rats with induced precocious puberty showed the same sexual feature as the rats that had normal puberty. NMA plays its role at the level of hypothalamus. Subcutaneous injection of NMA is an effective means to induce true precocious puberty in female rats.

OBJECTIVE To explore the incidence rate,pathogen distribution and characteristics of drug resistance of ventilator-associated pneumonia(VAP) patients due to acute lung injury and acute respiratory distress syndrome(ALI/ARDS) after severe injury,and analyze impact factors on VAP.METHODS All 183 cases with ALI/ARDS after severe injury from Jan 2004 to Mar 2008,were admiitted and given mechanic ventilation over 48 hours in our ICU and EICU.RESULTS VAP was found in 98 cases,accounted for 53.56%.Among them,42 were early-onset VAP and the other 56 were late-onset VAP.Altogether 276 pathogens were isolated,and most of them were Pseudomonas aeruginosa,Staphylococci aureus,Klebsiella pneumoniae,Acinetobacter baumannii and Escherichia coli.In 41 cases only one pathogen was isolated,the other 57 cases were with two or above pathogens.The revealed important risk factors were coma,prolonged mechanical ventilation,tracheotomy,antiacid treatment,use of antimicrobial agents and low albumin.CONCLUSIONS The incidence rate of VAP due to ALI/ARDS is high,and most of the isolated pathogens are drug resistant.Mixed infections are found commonly in these cases.

Objective To establish the preparation techniques for preparing the reference substance of platycodin-D.Methods Raw material of platycodi radix was extracted with 70 %MeOH.The concentrated extract passed through D101 macroporous resin column,then the 40 %alcohol eluate was separated by silica gel column chromatography with chloroform-methanol gradient elution.The fractions contained platycodin-D were collected and purified by HPLC.Results HPLC analysis and normalization of peak areas showed the purity of the platycodin-D was 98.8 %.Conclusions The preparation techniques are simple and high yield,can be used for preparing the reference substance of platycodin-D.

Object To study the causes for the occurrence of red skin and dark green skin of Panax quinquefolius L. during processing and its mechanism. Methods To observe the phenomena and analyze the result which simulated the processing condition of P. quinquefolius based on its components. Results The cross section of P. quinquefolius began to appear light red at 40 ℃, lasting 72 h. Whereas the time of browning was shortened with the temperature rising. The cross section of P. quinquefolius turned green while dipping in solution of Fe 3+ ion of 0 01 mol/L for 25 min. The time of turning green was shortened with the increasing concentration of Fe 2+ , Fe 3+ solution. Conclusion The results show that red skin of P. quinquefolius was caused by the Maillard reaction while drying at the excessive higher temperature. Whereas the complex reaction between phenolic substances in P. quinquefolius and metal ions during processing might result in dark green skin of P. quinquefolius. This expounds the mechanism of red skin and dark green skin turning during the P. quinquefolius processing in the theory.

OBJECTIVE:To observe the effectiveness and safety of azelastine combined with fluticasone in the treatment of allergic rhinitis(AR). METHODS:A total of 135 AR patients were selected from 3 hospitals during Jan. 2015-Jul. 2016, and divided into azelastine group,fluticasone group and drug combination group according to random number table,with 45 cases in each group. On the basis of decongestant Oxymetazoline hydrochloride spray,azelastine group was given Azelastine hydrochloride nasal spray,1 spray each nostril,morning and night;fluticasone group was given Fluticasone propionate nasal spray,1 spray each nostril,morning and night;drug combination was given Azelastine hydrochloride nasal spray combined with Fluticasone propionate nasal spray,with the same usage and dose. Three groups were treated for consecutive 30 d. Total nasal symptom score (TNSS) and total ocular symptom score (TOSS) decline indexes,nasal minimal cross-sectional area (NMCA),total nasal resistance(TNR)and the occurrence of ADR were compared among 3 groups. RESULTS:Some pa-tients were withdrawal from the trial;finally,127 patients were included in full analysis set,and 130 patients were included in safety set. After treatment,TNSS decline index of drug combination group was significantly higher than azelastine group and fluticasone group,with statistical significance(P<0.05). There was no statistical significance in TNSS decline indexes be-tween azelastine group and fluticasone group,as well as TOSS decline indexes among 3 groups(P>0.05). Before treatment, 3 groups suffered from nasal ventilation disorder to different extents,but there was no statistical significance in TNR or NMCA among 3 groups(P>0.05). After treatment,NMCA and TNR at 75,150 Pa of 3 groups were significantly lower than before,and TNR of drug combination group was significantly lower than azelastine group and fluticasone group,with statisti-cal significance(P<0.05). There was no statistical significance in NMCA among 3 groups(P>0.05). There was no statistical significance in the incidence of ADR among 3 groups(P>0.05). CONCLUSIONS:Both azelastine and fluticasone can effec-tively relieve nasal symptom as well as improve nasal ventilation disorder in AR patients;therapeutic efficacy of drug combi-nation is better than single drug,and it doesn't increase the incidence of ADR.
